SPECIFICATION forming part of Letters Patent No. 423,856,dated March 18, 1890.

Serial No. 336,375. (No modelJ To all whomf t may concern.-

Be it known that I, DAVID I-I. GOLES, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,

have invented new and useful Improvements in Sewing-Machines, of which the following is a specification.

This invention relates to a sewing-machine which is capable of producing miter-shaped 1o borders and simultaneously hemming the edges of the Work. l

The peculiar and novel construction of my sewing-machine is pointed out in the following specification and claims, and illustrated I5 in the accompanying drawings, in Which- Figure l represents a plan or top view. Fig. 1"L is a plan view of a portion of the Work when iinished. Fig. 2 is avertical section in the plane Qc Fig. l. Fig. 3 is a front view,

2o partly in section, showing the Working parts in a different position from the previous iigures. Fig. 4 is a partial vertical section in the plane y y, Fig. 2.

In the drawings, the letter A designates the base-plate, which is provided with a circular cavity a., and on Which rest the frames B B B2, the frames B B2 being litted into the frame B, as shown in Fig. l. The frame B is provided with a cross-bar b, from which projects 3o a cylindrical boss b to engage the cavity c in the base-plate A. Through the boss b eX- tends the vertical driving-shaft C, on the upper end of which is mounted a bevel-wheel c, engaging a bevel-wheel d, mounted on the horizontal shaft D, which has its bearings in the frame B and extends through the frames B B2. The frame B is provided at its rear ends with two Wheels b2 b2, which rest upon the base-plate A and are placed in such a po- 4o sition that said frame can be turned easily round on its boss b', and when it is turned round the shaft D remains in gear with the drivingshaft O.

From the rear ends of the frames B B B2 extend the goose-necks E E E2, which carry the needle-heads F F F2 and the shafts e e e2, which serve to impart motion to the needle-slidesff f2, and to which motion is imparted from a shaft G, which has its bearings 5oin arms e0, extending from the gooseneck E,

and is geared together with the shafts e e e2 by bevel-Wheels g g g2 and with the shaft D by gears g2, as shown in Figs. l and 2. From the goose-necks E E2 extend arms e0 co2, which engage circular grooves in the hubs of the bevel-wheels g g2, and these bevel-Wheels are feathered on the shaft G, so that they can follow the movements of the frames B B2 Without being thrown out of gear with the shafts e e2. 6o

Each of the frames B B B2 is provided with a throat-plate T T T2 and Wi th a shuttle-carrier S S S2, and motion is imparted to these shuttle-carriers by cams s s s2, which are l mounted on the shaft D, the cams s 32 being 65 feathered on this shaft and carried by forked arms S10 320, which extend from the frames B B2, respectively, and engage circular grooves in hubs of the cams s s2. (See Fig. 2.)

From the bottom of the frame B projects 7o a stud 72.', (preferably a roller-stitch) Which engages a groove or recess II in the base-plate A, and from the sides of said frame B project roller-studs 1l', Which engage grooves or slots t' in the sides of the frame B. From the bot- 75 tom of the frame B2 projects a roller-stud h2, Which engages a groove H2 in the base-plate A, and from the sides of said frame B2 project rollerstuds t2, which engage slots or grooves t2 in the sides of the frame B. On 8o the shaft D is loosely hung a pavvl K, which engages a segmental rack L, secured to or on the base-plate A, and a cam or eccentric k, Fig. 4,imparts to the pawl the required movement, so thatby its engagement With the rack L a step-by-step movement is imparted to the frames B B B2, causing the frame B to turn on its boss b as a center, While the frames B B2 are compelled to move with the frame B, and at the same time the needle-heads F F2 9o are carried in the direction of the grooves H vH2, respectively, by the action of the rollerstuds h 77.2, which are situated in the same vertical planes with the needle-slides f f2, respectively.

From the base-plate A rises a standard M, which is provided in its under surface with a groove m. This groove is directly over and in line with the groove H2 in the base-plate A, which engages the stud h2 of the frame B2. Ico

From the needle-head E2 extend two cylindrical projections f fi, one above and the otherbelow,which engage the eyes 0 o, formed on the hemmer O. From the eye o extend two arms 02, Fig. 3, carrying roller-studs o, which engage the groove m in the standard M. In the example shown in the drawings the hemmer is provided with two foldingguides 04, so that if the work to be sewed consists of two layers of muslin or other material the edges of both layers are turned in and hemmed simultaneously. By means of the slot m in t-he standard M the hemmer O is retained in the proper relation to the needle in the head F2, while it is free to move with this head as the sewing progresses.

l) P are the feed-rollers, which are geared together and on the shaft of one of which is mounted the ratchet-wheel p, Figs. l and 3.

Q is the feed-pawl, which engages the ratchet-wheel p and is attached to the feed-lever q, so that it can yield in one direction. The fulcrum q of the feed-lever is adjustable, so that the feed motion can be increased or decreased in the well-known manner. The inner end of the feed-lever engages the hub q2 of a segment q, the shank of which is guided in a socket qi, Fig. 3, and which is held in contact with the feed-cam Q5 by the action of a spring (f. The feed-cam is iirmly mounted on the shaft D.

The throat-plates T T T2 form the workplate, and by the act-ion ot' the feed-rollers the work receives a step-by-step movement in the direction of arrow l, Fig. l, and at the beginning of the operation the frames B B B2 ocn eupy the positions shown in Fig. 1, so thatthe first stitches will be in the position indicated by the letters yn vn n? in Fig. 1n. As the sewing progresses the needle in the needlehead F remains in the same vertical plane, and the length of the stitches produced by this needle is equal to the cloth-feeding motion; but the needles carried by the needleheads F F2 are moved after each stitch in the direction opposite to the cloth-feeding motion and a miter-shaped border is produced, as iudicated in Fig. l, and at the same time the edge of the work is henuned.

That I claim as new, and desire to secure by Letters Patent, isM
